Abstract
Methods and systems for improved optical efficiency and brightness of display systems are provided herein. Embodiments use laser light sources in substantially continuous mode, thereby increasing the maximum overall output of an optical system. Embodiments exploit the small étendue of laser sources to lower the loss of throughput of an optical system. Embodiments enable a scrolling color scheme that allows a display system to be illuminated with two or more colors at any given time, thereby increasing the brightness of the display system. Embodiments can be used with liquid crystal displays and/or digital mirror displays. Embodiments can be used in single-panel and/or two-panel display systems.
